摘要
对各向异性媒质中辐射问题的研究 ,求出磁偶极在各向异性媒质中辐射的具有张量形式的能流密度的普遍公式 ,在直角坐标系中 ,通过并矢计算 ,得出磁偶极在各向异性媒质中辐射的平均能流密度 ,并对磁偶极在各向异性媒质中的辐射作出了主要集中方向的判断 ,为研究各向异性媒质的开发应用提供了一个理论依据。
Research on the problem of radiation in anisotropic magnetic medium, the author derives a general formula for radiation energy flow density of magnetic dipole radiation in anisotropic medium with tensor form.In orthogonal coordinate, the average energy flow density of magnetic dipole radiation in anisotropic medium is thereby obtained through switching agorithm. with regard to the direction of magnetic dipole radiation in anisotropic medium, a judgement is made on the direction of its concentration. A thereotical basis is thus offered for studying the development and the application of anisotropic medium. The formula deriving here is tested and verified finnally.
